A nurse is collecting data on a client who has respiratory acidosis. Which of the following findings should the nurse expect?

Numbness of fingers

Abdominal pain

Dry skin

Lethargy

Answer and Explanation

The Correct Answer is D

Choice A reason: Numbness of fingers is not a sign of respiratory acidosis. It can be caused by other conditions such as peripheral neuropathy, Raynaud's syndrome, or carpal tunnel syndrome.

Choice B reason: Abdominal pain is not a sign of respiratory acidosis. It can be caused by other conditions such as gastritis, appendicitis, or gallstones.

Choice C reason: Dry skin is not a sign of respiratory acidosis. It can be caused by other conditions such as dehydration, eczema, or hypothyroidism.

Choice D reason: Lethargy is a sign of respiratory acidosis, as it indicates a low level of oxygen and a high level of carbon dioxide in the brain. Lethargy is a state of reduced mental and physical activity, which can progress to confusion, coma, or death if not treated.

Correct Answer is B

Explanation

The correct answer is B. Decreased deep tendon reflexes. Hyperkalemia can lead to muscle weakness and decreased reflexes, which is a common manifestation in patients with chronic kidney disease.

Choice A reason:

Wheezing is typically associated with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), not hyperkalemia. Hyperkalemia affects the muscular function and cardiac conduction rather than causing respiratory symptoms.

Choice B reason:

Decreased deep tendon reflexes occur due to the effect of hyperkalemia on the neuromuscular junction and muscle excitability. In hyperkalemia, the resting membrane potential of muscle cells is less negative, which makes them less responsive to stimuli.

Choice C reason:

Hypoactive bowel sounds are generally associated with gastrointestinal issues and are not a direct manifestation of hyperkalemia. While severe hyperkalemia can affect smooth muscle function, it is not typically characterized by changes in bowel sounds.

Choice D reason:

Cerebral edema is not a manifestation of hyperkalemia. It is usually caused by traumatic brain injury, infections, or other neurological conditions. Hyperkalemia primarily affects muscular function and cardiac conduction.

Normal serum potassium levels range from about 3.5 to 5.0 mmol/L. Hyperkalemia is defined as serum potassium levels above 5.0 mmol/L.

A. Metabolic alkalosis B. Respiratory acidosis C. Metabolic acidosis D. Respiratory alkalosis

Correct Answer is A

Explanation

Choice A reason: Metabolic alkalosis is a condition in which the blood pH is elevated due to an excess of bicarbonate or a loss of acid. It can be caused by nausea and vomiting, as they result in the loss of gastric acid and the retention of bicarbonate.

Choice B reason: Respiratory acidosis is a condition in which the blood pH is lowered due to an accumulation of carbon dioxide. It can be caused by hypoventilation, airway obstruction, or lung diseases. It is not related to nausea and vomiting.

Choice C reason: Metabolic acidosis is a condition in which the blood pH is lowered due to an excess of acid or a loss of bicarbonate. It can be caused by diabetic ketoacidosis, renal failure, or lactic acidosis. It is not caused by nausea and vomiting.

Choice D reason: Respiratory alkalosis is a condition in which the blood pH is elevated due to a loss
carbon dioxide. It can be caused by hyperventilation, anxiety, fever, or aspirin overdose. It is not common in clients who have nausea and vomiting.
